are the valves, spring, lifters, valve guides all interchangeable with 1g heads and 2g heads?

Unless you are lucky enough to have a head off a Hyundai. I will double check but im pretty sure I snagged one the other day that already has the 12mm head bolt holes.The 6bolt block has larger head bolts and more than a few report having to widen the bolt holes for it to be properly installed, key word properly. . . Some have not. But also remember that the head receives oil from one of those holes (farthest left on the radiator side). If it's a tighter fit, then you're likely impeding oil flow to the head: lifter tap, turbo oiling issues, possibly throwing rockers, valve float is possible because the lobe will strike the rocker instead of ramping up the lift. . .
Think it was already awnsered in post #9.can you guys get a grip, and focus on what the post was meant to be, which is the valvetrain be interchangeable, man I wish defiant was back or at least a replacement that would stop post like this.
To the OP yes they are interchangeable, I honestly can't think of one part that will not work from changing one to another.
Yup right there.yes the parts to swap from a 1g head to a 2g head
The plenum is the size of 1G and runners of a 2G and looked to have the same 1G NT throttle body.
Like this? The plenum is larger than a 1g, the runners are 2g and shorter than either, the throttle body is already a 60mm.You must be logged in to view this image or video.
